A fine-grained genetic algorithm based algorithm which is for the parameters optimization problem of agent model is proposed. The fine-grained genetic algorithm is used to solve the parameters optimization problem of agent model. As to the parameters optimization problem of the agents colony model, the first step is to define the concept of "the parameters mode of the combat agents colony" to describe the parameters of the combat agent colony model. Then the genetic algorithm is used to solve the optimization problem with the parameters mode of the combat agent colony model as the genetic individual. Besides the algorithm, the algorithm dispatch tactic is also considered. And the two level sequence dispatch tactic and the two level nesting dispatch tactic are put forward for those complex parameters optimization problem. At last, the model parameters optimization under antagonism codition is studied. The means to solve this problem is to translate it into a kind of antagonism problem, then use the competitive co-evolutionary genetic algorithms to solve it.

Third, the results also revealed that the toddlers'rhythmicity, intensity of reaction, quality of mood and the parenting style of punishment were always lead to the incidence of the deregulation incidence of social-emotional development. In the end, the binary logistic result told us that toddlers'gender, age, apporoach and withdrawal, persistence, threshold of responsiveness, the parenting of refused, encourage independence and explore and low-voltage-induced all can lead to the incidence of the competence.(2) The degree of effect caused by genetic and environmental factors on the toddlers'social - emotional development were revealed by the structural equation model.

Genetic cluster analysis is similar based on the results of morphological and DNA markers, the five populations could be divided into three groups. But there are different groups sort of individual locations, reflecting the similarities and difference about the analysis of the relationship between population with the two kinds of markers, It could be concluded that there was coupling and relevance to some extent in evaluating genetic diversity with the same experiment sampling by morphological and SSR marker variation. However, there was also differences. In research, the two can complement each other.8.

新疆野扁桃遗传多样性不同研究分析方法结果的比较与评价表型与DNA二种水平的遗传标记方法揭示的遗传多样性水平有差异,表型性状比DNA分子标记具有更大的变异性;其受到环境的影响较大,也即对环境更敏感。2种水平的遗传标记聚类结果将野扁桃5个不同分布群体均可分为3个大类群,但是出现有个别不同的群体排序位置,反映了2种标记在分析种群间关系上的异同性,从本研究结果来看,说明表型与DNA标记有一定的耦合性和相关性,但也存在差异,在研究上可以互为补充。8。

The average percentage of polymorphic bands are 72.06% for ISSR and 66.67% for RAPD respectively. The genetic diversity of ginkgo revealed by ISSR (the average effective number of alleles is 1.8780, the average Nei"s gene diversity is 0.4652, and the average Shannon"s information index is 0.6574) are all higher than those by RAPD (the average effective number of alleles is 1.7842, the average Nei"s gene diversity is 0.4317, and the average Shannon"s information index is 0.6211), while the standard errors of the parameters estimated by ISSR were lower. Therefore, ISSR molecular markers are more suited than RAPD molecular markers when testing the genetic diversity of ginkgo populations and determining the genetic relationship of among populations or among individuals which are much similar hereditarily.
本文应用RAPD和ISSR两种分子标记技术,选取中国5个可能的野生银杏居群共计75个样品,对其遗传多样性进行了研究,得出以下结论:(1)用筛选出的12个RAPD引物和10个ISSR引物进行PCR扩增,分别扩增出65条和68条重复性高、清晰的条带,多态性位点百分率分别66.67%和72.06%,ISSR揭示的银杏遗传多样性(平均有效等位基因数目为1.8780,平均基因多样度为0.4652,平均信息指数为0.6574)高于RAPD所得到的结果(平均有效等位基因数目为1.7842,平均基因多样度为0.4317,平均信息指数为0.6211),其所估算参数的标准差要低于RAPD所估算出的值,因此,在研究亲缘关系非常近的银杏物种的遗传多样性并试图确定居群间或个体间的遗传关系时,ISSR分子标记技术比RAPD分子标记技术更为合适。
